Hi all, I have a topology with loops, and my version of Pox is up-to-date. I run pox in this way:
./pox.py forwarding.l3_learning openflow.discovery --eat-early-packets openflow.spanning_tree --no-flood --hold-down after running pox I start mininet and I try to build a tcp connection with iperf from 2 hosts to the same host. But I can't reach it (no route to host) and I have this error: ERROR:openflow.of_01:[00-00-00-00-00-02 5] OpenFlow Error: [00-00-00-00-00-02 5] Error: header: [00-00-00-00-00-02 5] Error: version: 1 [00-00-00-00-00-02 5] Error: type: 1 (OFPT_ERROR) [00-00-00-00-00-02 5] Error: length: 76 [00-00-00-00-00-02 5] Error: xid: 2046 [00-00-00-00-00-02 5] Error: type: OFPET_BAD_REQUEST (1) [00-00-00-00-00-02 5] Error: code: OFPBRC_BUFFER_UNKNOWN (8) [00-00-00-00-00-02 5] Error: datalen: 64 [00-00-00-00-00-02 5] Error: 0000: 01 0e 00 48 00 00 07 fe 00 00 20 40 00 18 d2 87 |...H...... @....| [00-00-00-00-00-02 5] Error: 0010: 03 64 03 d1 00 00 00 00 00 06 ff ff 00 00 08 00 |.d..............| [00-00-00-00-00-02 5] Error: 0020: 00 06 00 00 00 00 00 00 0a 00 00 65 00 00 13 89 |...........e....| [00-00-00-00-00-02 5] Error: 0030: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 80 00 |................| Sometimes it happens just for one of the sender, sometimes for both of them. Do you know how can I solve it? Thank you and Happy Xmas -- Silvia Fichera
